Aluminum wire is usually used for rigging and it will have a piece of square stock epoxied to the end of it that would fit into a larger piece of square stock that is epoxied inside of the puppet. The wire can then be attached to a heavy base or screwed onto the animation surface.

The rigging is visible in some of the shots, so you need to take it out in Photoshop or After Effects or a similar program, by shooting an empty plate first - a shot without the puppets in it - then either masking or erasing through from the frame with the puppet to the empty one. Doesn't work with camera moves unless you have a moco rig that can duplicate the move.
